Proceedings Article | 22 July 2010 Paper

High voltage pulse power supply of piezoelectric transformer based on adaptive frequency tracking control

Ze-rong Guo, Chun-yu Bai, Hua-bo Li

The damage capacity of weapon systems is enhanced when all-electronic safety and arming device (ESAD) is applied, so that ESAD has been favored by the military power. ESAD must ensure the normal work in the stipulation of -40 °C ~ +60°C temperature. When high voltage pulse power supply of piezoelectric transformer (PT) is used in ESAD the charging time has the large dispersion and affects the striking capability of weapon systems. In order to control the inconsistency charging time due to environment temperature change the adaptive frequency tracking control system for high-voltage pulse power supply of PT is designed. Theoretical calculation of current lag angle under zero voltage switching condition for resonant current is derived. Sampling circuit and control circuit are designed by applying the phase-locked loop (PLL) control technology. Experiment results have proved that this control can ensure the consistency of converter output under different environment.

In modern warfare the performance of weapon system safe and arming device has been put forward higher requirements because the battlefield environment has become increasingly sophisticated. The safe and arming device should have good safety of mechanical, electrical, thermal and other aspects and reliable initiation. This paper analyses the laser initiation of three ways, the laser could initiate the insensitive acceptable charge for the in-line ignition system, so that the laser in-line ignition can be realized and the laser in-line ignition all electronic safe and arming device is built. Then, studies the composition and working principle of the laser in-line ignition all electronic safe and arming device and the various subsystems in-depth. The laser in-line ignition all electronic safe and arming device can be applied to fixed-point, directional and multi-point initiation and has laid an important foundation of the theory and engineering in the future weapon system.
